In the context of hairstyles, the usage of the term pigtail (or twintail or twin tail ) shows considerable variation. The term may refer to a single braid, but when used in the plural it often refers to twin bunches of hair on opposite sides of the head. For some users, the term "pigtails" applies only if the hair is braided,  but there is not widespread agreement on this (in places where this usage is common, unplaited pairs are called bunches and a single bunch, regardless of position on the head, is called a ponytail ).
Because of the significant association of insulin resistance and obesity with PCOS, therapy to reduce insulin resistance is appropriate. Diet, exercise, and weight loss should be prescribed for all women with PCOS.

A modest weight loss of 7 to 15 pounds with an appropriate exercise program are all that is needed to relieve menstrual and biochemical abnormalities. 8
